TMC310911 is a potent and orally active HIV type-1 (HIV-1) protease inhibitor with EC50 values ranged from 2.2 nM to 14.2 nM for wild-type HIV-1. TMC310911 has potent activity against a wide spectrum of recombinant HIV-1 isolates. TMC310911 has strong antiviral activity[1][2].
For a panel of 2,011 recombinant isolates with decreased susceptibility to at least one of the currently approved protease inhibitors (PIs), the FC in TMC310911 EC50 is ≤4 for 82% of isolates and ≤10 for 96% of isolates. The fold change (FC) in TMC310911 EC50 is ≤4 and ≤10 for 72% and 94% of isolates with decreased susceptibility to Darunavir, respectively.

TMC310911, a novel human immunodeficiency virus type 1 protease inhibitor, shows in vitro an improved resistance profile and higher genetic barrier to resistance compared with current protease inhibitors
Antimicrob Agents Chemother 2011 Dec;55(12):5723-31.PMID:21896904DOI:10.1128/AAC.00748-11.
TMC310911 is a novel human immunodeficiency virus type 1 (HIV-1) protease inhibitor (PI) structurally closely related to darunavir (DRV) but with improved virological characteristics. TMC310911 has potent activity against wild-type (WT) HIV-1 (median 50% effective concentration [EC(50)], 14 nM) and a wide spectrum of recombinant HIV-1 clinical isolates, including multiple-PI-resistant strains with decreased susceptibility to currently approved PIs (fold change [FC] in EC(50), >10). For a panel of 2,011 recombinant clinical isolates with decreased susceptibility to at least one of the currently approved PIs, the FC in TMC310911 EC(50) was ≤ 4 for 82% of isolates and ≤ 10 for 96% of isolates. The FC in TMC310911 EC(50) was ≤ 4 and ≤ 10 for 72% and 94% of isolates with decreased susceptibility to DRV, respectively. In vitro resistance selection (IVRS) experiments with WT virus and TMC310911 selected for mutations R41G or R41E, but selection of resistant virus required a longer time than IVRS performed with WT virus and DRV. IVRS performed with r13025, a multiple-PI-resistant recombinant clinical isolate, and TMC310911 selected for mutations L10F, I47V, and L90M (FC in TMC310911 EC(50) = 16). IVRS performed with r13025 in the presence of DRV required less time and resulted in more PI resistance-associated mutations (V32I, I50V, G73S, L76V, and V82I; FC in DRV EC(50) = 258). The activity against a comprehensive panel of PI-resistant mutants and the limited in vitro selection of resistant viruses under drug pressure suggest that TMC310911 represents a potential drug candidate for the management of HIV-1 infection for a broad range of patients, including those with multiple PI resistance.
Safety and pharmacokinetics of the HIV-1 protease inhibitor TMC310911 coadministered with ritonavir in healthy participants: results from 2 phase 1 studies
J Acquir Immune Defic Syndr 2014 Mar 1;65(3):299-305.PMID:24121757DOI:10.1097/QAI.0000000000000011.
Objectives: To evaluate safety, tolerability, and pharmacokinetics of TMC310911, a novel human immunodeficiency virus type-1 protease inhibitor. Methods: Healthy participants aged 18-55 years with body mass index 18-30 kg/m were enrolled in 2 phase 1 studies. In the first-in-human, single-dose study, 18 participants received placebo or TMC310911 (75-2000 mg) in the double-blind phase and 8 participants received 300 or 600 mg of TMC310911 [administered alone or with 100 mg ritonavir twice daily (bid)] in the subsequent open-label phase. The multiple-dose double-blind study included 5 successive treatment sessions wherein healthy participants received placebo or TMC310911 [300 mg bid, 600 mg once daily or 150 mg bid (plus 100 mg ritonavir bid), 900 mg bid (alone) or 300 mg bid (plus ritonavir 50 mg bid)]; in all sessions, TMC310911 and ritonavir were administered for 6 and 9 days, respectively. Results: In the single-dose study, no dose-limiting toxicity was observed up to 2000 mg of TMC310911. Systemic exposure to TMC310911 generally increased in a dose-proportional manner after the single- or multiple-dose administrations. Coadministration of ritonavir increased the systemic exposure to TMC310911. The mean Cmax and area under plasma concentration-time curve values (single-dose: 1200 mg TMC310911) were higher under fasted conditions than in fed condition. In both studies, most treatment-emergent adverse events were related to gastrointestinal system. Conclusions: TMC310911 exhibited a linear pharmacokinetic profile after the single- (up to 2000 mg) and multiple-dose (up to 900 mg) administrations; ritonavir improved the pharmacokinetic profile of TMC310911. TMC310911 was generally safe and tolerable when administered with or without ritonavir.
Antiviral activity, pharmacokinetics, and safety of the HIV-1 protease inhibitor TMC310911, coadministered with ritonavir, in treatment-naive HIV-1-infected patients
J Acquir Immune Defic Syndr 2014 Mar 1;65(3):283-9.PMID:24121756DOI:10.1097/QAI.0000000000000003.
Objectives: TMC310911 is a novel HIV type-1 (HIV-1) protease inhibitor with broad in vitro antiviral activity. In this phase 2a, open-label randomized study, the antiviral activity, pharmacokinetics, and safety and tolerability of ritonavir-boosted TMC310911 was assessed. Methods: In this study, treatment-naive HIV-1 patients (aged 18-60 years) received 1 of the 4 dosing regimens of TMC310911: 150 mg twice-daily (bid) (n = 8), 300 mg bid (n = 8), 75 mg bid (n = 9), or 300 mg once-daily (qd) (n = 8), for 14 days, all coadministered with 100 mg of ritonavir, as only antiretroviral therapy. Results: The mean change from baseline in HIV-1 RNA (log10 copies per milliliter; primary efficacy endpoint) was -1.30 (75 mg bid), -1.14 (150 mg bid), -1.07 (300 mg bid), and -1.06 (300 mg qd) on day 8 and -1.53 (75 mg bid), -1.79 (150 mg bid), -1.69 (300 mg bid), and -1.55 (300 mg qd) on day 15. At steady state (day 14), the mean maximum plasma concentration and mean area under the plasma concentration-time curve from 0 to 12 hours tended to increase dose proportionally for bid doses; TMC310911 daily exposures for the 300 mg qd treatment and 150 mg bid treatment were comparable. The most common (≥ 10%) treatment-emergent adverse events were fatigue (27.3%) and nausea (12.1%); no deaths or serious treatment-emergent adverse events were reported in this study. Conclusions: Combination treatment with TMC310911 and ritonavir showed potent antiviral activity (>1.5 log10 copies/mL decrease in plasma HIV-1 RNA) at all evaluated doses, and treatment was generally safe and well tolerated.
Possibility of HIV-1 protease inhibitors-clinical trial drugs as repurposed drugs for SARS-CoV-2 main protease: a molecular docking, molecular dynamics and binding free energy simulation study
J Biomol Struct Dyn 2021 Sep;39(15):5368-5375.PMID:32627689DOI:10.1080/07391102.2020.1786459.
Initially, the SARS-CoV-2 virus was emerged from Wuhan, China and rapidly spreading across the world and urges the scientific community to develop antiviral therapeutic agents. Among several strategies, drug repurposing will help to react immediately to overcome the COVID-19 pandemic. In the present study, we have chosen two clinical trial drugs against HIV-1 protease namely, TMB607 and TMC310911 to use as the inhibitors of SARS-CoV-2 main protease (Mpro) enzyme. To make use of these two inhibitors as the repurposed drugs for COVID-19, it is essential to know the molecular basis of the binding mechanism of these two molecules with the SARS-CoV-2 Mpro. To understand the binding mechanism, we have performed molecular docking, molecular dynamics (MD) simulations, and binding free energy calculations against the SARS-CoV-2 Mpro. The docking results indicate that both molecules form intermolecular interactions with the active site amino acids of Mpro enzyme. However, during the MD simulations, TMB607 forms strong interaction with the key amino acids of Mpro, and remains intact. The RMSD and RMSF values of both complexes were stable throughout the MD simulations. The MM-GBSA binding free energy values of both complexes are -43.7 and -34.9kcal/mol, respectively. This in silico study proves that the TMB607 molecule binds strongly with the SARS-CoV-2 Mpro enzyme and it may be suitable for the drug repurposing of COVID-19 and further drug designing.Communicated by Ramaswamy H.
